Prosperity Bancshares used its Q4 2025 call to explain its proposed acquisition of Stellar Bancorp and the expected impact on earnings, margins, and capital. Management said the deal would move the combined bank’s Houston deposit rank from ninth to fifth and make it the largest Texas-based bank in that market. Stellar’s stronger margin, around 4.2%, is expected to lift Prosperity’s net interest margin above 3.5% in 2026, helped by Stellar’s granular loan book and non‑interest‑bearing deposits. For 2027, Prosperity is targeting $7.34 in EPS and a return on average tangible capital rising from 13% to about 17%, arguing the premium price (about 18x one‑year‑forward earnings and a 4.5‑year earn‑back) is justified by franchise value. Executives emphasized strong cultural and credit alignment, extensive leadership relationships, retention and non‑compete agreements, and ample liquidity and capital, while also outlining standard regulatory, integration, and execution risks in detailed forward‑looking statements.
